std::ostringstream的基础问题：这是在对变量赋值吗？

xjmaming 2011-09-13 04:25:22

std::ostringstream tmp_outStreamAfterAPI("");
tmp_outStreamAfterAPI<<""
<<"\t[out] out_stuAuthParamOut\n"
<<"\t iResultCode = " <<(pContext->t_oAuthParamOut).iAuthErrorCode <<"\n"
<<"\t 0 : PBXMember table DBError"<<"\n"
<<"\t 1 : No record in PBXMember"<<"\n"
<<"\t 2 : PBXLink table DBError"<<"\n"
<<"\t 3 : No record in PBXLink"<<"\n"
<<"\t 4 : UserGroup table DBError"<<"\n"
<<"\t 5 : No record in UserGroup"<<"\n"
<<"\t 6 : Enterprise table DBError"<<"\n"
<<"\t 7 : No record in Enterprise"<<"\n"
<<"\t 8 : Enterprise is not active"<<"\n"
<<"\t 9 : Enterprise validity is invalided"<<"\n"
<<"\t 10: Member table DBError"<<"\n"
<<"\t 11: No record in Member"<<"\n"
<<"\t 12: Member is not active"<<"\n"
<<"\t 13: User table DBError"<<"\n"
<<"\t 14: No record in User"<<"\n"
<<"\t 15: Success"<<"\n"
<<"\t 16: No record in SP"<<"\n"
<<"\t 17: Virtual number"<<"\n"
<<"\t 18: System error"<<"\n"
<<"\t strFailedTbName = " <<(pContext->t_oAuthParamOut).strFailedTbName <<"\n"
<<"\t cCallerTerminalType = " <<(pContext->t_oAuthParamOut).cTerminalType <<"\n"
<<"\t 0: Mobile"<<"\n"
<<"\t 1: DID Fix Number"<<"\n"
<<"\t 2: GMN"<<"\n"
<<"\t 3: GMN + PNPN"<<"\n"
<<"\t strGMNNumber = " <<(pContext->t_oAuthParamOut).strGMNNumber <<"\n"
<<"\t strPNPN = " <<(pContext->t_oAuthParamOut).strPNPN <<"\n";

iResultCode，strFailedTbName，cCallerTerminalType，strGMNNumber，strPNPN是局部变量，<<"\t iResultCode = " <<(pContext->t_oAuthParamOut).iAuthErrorCode <<"是在对iResultCode赋值吗？

呵呵，赋值操作符在引号中啊。

是在连续地向一个字符串流输出字符串，而在输出的字符串中有等号 = 就把你迷惑了
